Statement-1: Nitrogen atom has higher ionization energy than fluorine atom. 

Statement-2: Nitrogen atom has extra stable electronic configuration due to half filled p-subshell.

When compared to N, which has an extra electron it is easier to release, F is more stable and half-filled. However, it takes more energy to lose an electron.

Half-full p subshells in nitrogen are more stable than partially filled ones. On the other hand, oxygen is able to quickly lose one electron and achieve a more stable half-filled e configuration.
